Hello everybody,

I have a signal as shown below, I need to plot two curves, one passes the max values of the signal and the other throughout the min values (it likes an envelope for the signal).

Thanks in advance.

I appreciate for your response, I know the envelope command, but what I need is the curve to be more smooth when passes the max and min values like the below.
